[jdom-interest] Tracking changes

Supose I have an xml file like this:
<?xml ...
    <row key="1">
    <row key="2">
Then I do the following operations:
    - delete row 2
    - modify row 1
    - add row 3
Then I have to save the xml file in the RDBMS. Currently the only way I have
is to delete all the rows and make an insert for each row in the final xml.
This is very costly in more complicated examples (header and lines, etc.)
I would like to do three operations (delete, update and insert) but for that
I need to track the modifications on the xml.

No JDOM doesn't have any feature like this.  Then I might ask, what are you
trying to accomplish.  Doing essentially a diff on an xml document doesn't
seem like a very good way to track changes to data.  Or are you trying to do
something else?

we are currently using JDOM in order to manage a XML retrieved from a
database. For performance, we would like to track the changes as they occur,
does JDOM provide any mechanism for this tracking. I was thinking in
something like a listener that gains control each time the document is
If this mechanism doesn't exist, I'm considering to do a wrapper but this
would implie duplicate all the api. Have you any other ideas? Do you know
somebody working in this line?
